With a title like that I had to play this .. I possess no rhythm or feeling for music .. and turns out, I was right. Still super cool. And very creative!
I think you had some issues importing the assets into Unity, they seem oddly blurry. Make sure to set the texture type to "Sprite (2D and UI)". For pixel graphics I also usually set the Filter from "Bilinear" to "Point" to keep the sharpness and keep it from going blurry when scaling.
